My wife has a 98 Audi A6 Quattro with 118,000 miles on it. We just got it and it is running rough. I am going to change the plugs and the fuel filter this weekend. Any tips on how hard either of these will be. I am a pretty good mechanic but when I look at all the cosmetic coverings on the motor it looks like a pain. Can someone tell me where the fuel filter is located on it and how hard the plugs are to change. I don't know if I should replace the plug wires also or not they are so darn expensive. Any and all help would be appreciated! Thanks!

 

Help! Anyone???

 

spark plugs change take aprox. 20 min. Fuel filter are located at rear on the side.

 

Great! Thanks! Do I have to remove anything to get too the plugs on the motor or can it all be reached from the sides? Should I replace the plug wires as well? If so are there cheaper wires out there that can be used than what they recommend for Audi? I appreciate the response tremendously!!!

 

Also do you know what gap the plugs need to be set at? Thanks!

 

most spark plugs are ready to install. Go for NGK for audi A6. All u need to do, is take off plastic engine cover (twist four plastic screws on the top). There u can see all spark plugs. There is no reason for change wires.
